Quick Detail

Description

The 3300 XL 8 mm Proximity Probe (330101-48-71-20-02-05) is a high-precision eddy current transducer designed for industrial automation, predictive maintenance, and real-time machinery monitoring. It delivers an output voltage directly proportional to the distance between the probe tip and a conductive surface, enabling accurate static position and dynamic vibration measurements on rotating equipment, pumps, turbines, and compressors.

Featuring an overall case length of 7.1 inches with a 4.8-inch unthreaded section, this probe is ideal for installations where compact yet robust positioning is required. The 3/8-24 UNF threaded case ensures secure mounting, while the 2.0-meter (6.6-foot) standard cable with Miniature ClickLoc connector enables easy integration with 3300 XL transducer systems. Certified to CSA, ATEX, and IECEx standards, the probe ensures reliable operation in hazardous and extreme temperature environments (-52°C to +177°C / -62°F to +350°F).

Technical features include a 2 mm (80 mils) linear range, 50 Ω output resistance, minimal supply sensitivity (<2 mV per volt), and 69.9 pF/m extension cable capacitance, delivering consistent and high-fidelity signal transmission. The probe incorporates TipLoc molding for robust probe tip bonding and CableLoc technology providing 330 N (75 lbf) pull strength, ensuring secure cable attachment. Optional FluidLoc cables prevent oil or liquid ingress, protecting both the probe and the monitored machinery. Fully backward-compatible with 3300 series 5 mm and 8 mm probes, it allows system upgrades without recalibration, making it a versatile solution for modern industrial monitoring systems.

Applications

1. Radial Vibration Monitoring
Measures radial shaft displacement with high precision up to 2 mm linear range, enabling early detection of imbalance, bearing wear, or misalignment in turbines and compressors.

2. Axial Position Measurement
Monitors axial (thrust) displacement in fluid-film bearings to prevent overload and ensure reliable operation of pumps, compressors, and high-speed machinery.

3. Keyphasor Signal Reference
Provides accurate phase reference for Keyphasor signals, supporting vibration analysis, rotor balancing, and speed measurement in critical rotating equipment.

4. Hazardous Area Deployment
CSA, ATEX, and IECEx approvals allow safe use in explosive or high-risk environments, such as oil and gas, chemical plants, and petrochemical facilities.

5. Compact and Space-Constrained Installations
With a 4.8-inch unthreaded length and 7.1-inch overall case, the probe is suitable for restricted mounting spaces where traditional probes cannot fit, maintaining measurement integrity.

Specifications

Competitive Advantage

1. Extreme Environmental Endurance
Operates reliably from -52°C to +177°C (-62°F to +350°F), sustaining performance in harsh industrial environments without signal degradation.

2. Robust Mechanical Design
TipLoc and CableLoc technologies provide 330 N (75 lbf) pull strength, preventing cable detachment and ensuring long-term mechanical stability.

3. High Accuracy and Signal Consistency
Minimal supply sensitivity (<2 mV per volt) and 2 mm linear range allow precise static and dynamic measurements for reliable predictive maintenance.

4. Backward Compatibility for Cost Efficiency
Fully compatible with existing 3300 series 5 mm and 8 mm probes and extension cables, enabling system upgrades without recalibration or replacement of ancillary components.

5. Optional Fluid Protection
FluidLoc cables prevent oil or process liquid ingress, maintaining signal integrity and protecting the machinery in critical applications, reducing downtime and maintenance costs.
